1.good rheological property and thixotropic property.
2. acid resistance: ph 2-4.
3.salt resistance: the addition of salt will not decrease but rather increases the viscosity of cmc aqueous solution
4.thermal resistance.
5. high transparency.
6 .antibacterial.
with improvement of people’s living standard, the requirements of daily necessities is also increasing constantly.
as a kind of daily necessity, toothpaste’s use value is not limited to mouth cleaning. it gradually becomes more functional and healthy.
there are many new types of toothpaste like: medicinal toothpaste, anticalculus toothpaste, anti-inflammatory and blood staunching toothpaste and complete care toothpaste,which raise new requirement of cmc, the main ingredient of toothpaste.
application:
as a thickening agent, cmc is widely used in toothpaste, and mainly takes effects of excipients and bonding. cmc can make toothpastes have a certain consistency, keep pastes into strips, and have good skeleton to prevent collapse and thinning out of toothpastes, so that can make the pastes keep delicate and smooth.
